Description

THERMALLY INSULATIVE INNER LINING FOR USE IN AN EXHAUST SILENCER OF A HERMETIC RECIPROCATING COMPRESSOR
The present invention relates to a hermetic reciprocating compressor for use in a refrigeration appliance, in particular a domestic refrigerator. The present invention more particularly relates to a technique for improving a thermodynamic efficiency of the hermetic reciprocating compressor.
In a conventional hermetic reciprocating compressor, the exhaust silencer is usually formed into the cylinder block. In such configuration, the compression chamber and the exhaust silencer are typically connected via an exhaust refrigerant passage formed into the cylinder block. Thereby, a compact configuration is attained.
CN1769694 (A) discloses a hermetic reciprocating compressor. In this compressor the exhaust silencer is formed into the cylinder block.
A drawback of this configuration is that in the compression phase the thermal energy of the hot and pressurized refrigerant exhausted from the compression chamber is partly dissipated to the cylinder block as it is conveyed via the refrigerant passage into a cavity of the exhaust silencer. Thus, the temperature of the refrigerant inside the cavity decreases and the thermodynamic efficiency of the overall refrigeration cycle degrades.
A further drawback of this configuration is that with the commencement of the subsequent suction phase the heat dissipated to the cylinder block is partly transferred to the refrigerant being conveyed into compression chamber. Thus, a density of the refrigerant taken into the compression chamber decreases and a thermodynamic efficiency of the overall refrigeration cycle degrades.
An objective of the present invention is to overcome the aforementioned problems of the prior art and provide a technique which improves the thermodynamic efficiency of the hermetic reciprocating compressor.
This objective have been achieved by the thermally insulative inner lining as defined in claim 1, the hermetic reciprocating compressor as defined in claim 11, and the refrigeration appliance as defined in claim 12. Further achievements have been attained by the subject-matters respectively defined in the dependent claims.
In the technique of the present invention, the thermodynamic efficiency is improved by utilizing a thermally insulative inner lining inside the exhaust silencer of the hermetic reciprocating compressor for reducing a heat transfer from the refrigerant inside the cavity of the exhaust silencer to the metal case enclosing the cavity. The thermally insulative inner lining also has a function to damp the acoustic vibrations of the refrigerant.
In an embodiment, the thermally insulative material of the inner lining has a coefficient of thermal conductivity which is lower than that of the cylinder block. In a version of this embodiment, thermally insulative material is plastic. In another version of this embodiment, the plastic is polyamide or one of its derivatives.
In another embodiment, thermally insulative inner lining has a capsule-like shape which from-fittingly matches an inner surface of the exhaust silencer.
By virtue of the thermally insulative inner lining, the thermodynamic efficiency of the hermetic reciprocating compressor has been improved.

The compression chamber (5) and the intake port (7) are in fluid communication through an exhaust refrigerant passage (9) (Figs. 1 to 3; Figs. 6 to 7).
The thermally insulative inner lining (1) of the present invention comprises a main body (10) made of a thermally insulative material. The main body (10) comprises an outer surface (11) which form-fittingly matches an inner surface (12) of the cavity (6), a hollow portion (13) which is formed into the main body (10) to acoustically damp the exhaust refrigerant received through the exhaust refrigerant passage (9) and an inlet port (14) and an outlet port (15) which are formed into the main body (10) and open into the hollow portion (13). The inlet port (14) and the outlet port (15) respectively face the intake port (7) and the exhaust port (8) (Figs. 1 to 8).
The hermetic reciprocating compressor (3) of the present invention comprises the thermally insulative inner lining (1) (Figs. 1 to 8).
In an embodiment, the thermally insulative material of the inner lining (1) has a coefficient of thermal conductivity which is smaller than a coefficient of thermal conductivity of the cylinder block (4). In a version of this embodiment, the cylinder block (4) is made from metal and the thermally insulative material is plastic. In another version of this embodiment, the plastic is polyamide or one of its derivatives.
In another embodiment, the outer surface (11) of the main body (10) form-fittingly matches an inward surface (16) of a lid (17) of the exhaust silencer (2) (Figs. 3 to 5).
In another embodiment, the main body (10) further includes two coaxially aligned through-holes (18) for inserting a fixing bolt (not shown) to fasten the lid (17) of the exhaust silencer (2) to the cylinder block (4) (Fig. 3). In this embodiment, the cylinder has a threaded bore (19) which is coaxially aligned with the through-holes (18) (Fig. 3).
For assembling the hermetic reciprocating compressor (3), the thermally insulative inner lining (1) is inserted into the cavity (6) of the exhaust silencer (2). Next, the lid (17) is placed to leak-tightly close the cavity (6). Thereafter, the lid (17) and the cylinder block (4) are fastened together by utilizing a bolt (not shown).
In another embodiment, the hollow portion (13) is hermetically enclosed through the main body (4) except for the inlet port (14), the outlet port (15) and the through holes (18) which open into the hollow portion (13) (Figs. 4 and 5).
In another embodiment, the main body (10) is capsule-shaped.
The present invention also provides a refrigeration appliance (not shown) which includes the hermetic reciprocating compressor (3) of the present invention.
In another embodiment, the refrigeration appliance is provided as a domestic refrigerator (not shown).
By virtue of the thermally insulative inner lining (1) of the present invention, the thermal energy of the hot pressurized refrigerant inside the exhaust silencer (2) is prevented from dissipating into the cylinder block (4). Thereby, a density of the refrigerant taken into the compression chamber (5) has been prevented from decreasing, and a thermodynamic efficiency of the hermetic reciprocating compressor (3) has been improved.
